The mean finish time was 185.52 with a standard deviation of 0.327 minute. the winning car driven by chris finished in 185.13. the previous year race had a mean finish time of 110.3 with a standard deviation of 0.106. the winning car that year driven by karen finished in 110.13 minutes. find their respective z-scores. chris - z-score karen “- z-score

Chris: -1.1315.

Karen: -1.6038.

Step-by-step explanation:

The z-score = (x - m) / d      where m = the mean, d = the standard deviation and x is the individual score.

Chris: z-score = (185.13 - 185.52) / 0.327

= -1.1315.

Karen: z-score = (110.13 - 110.3) / 0.106

= -1.6038.
